Panel mats connectable with interlocking and pinning elements

Abstract

A lightweight universal panel mat made of plastic or elastomeric material and having a first section that provides a relatively flat, textured or structured top surface to facilitate movement over the upper surface and a second section having geometry that includes a plurality of cells having top surfaces that support the first section. The mats also include first, second, third and fourth sides forming a perimeter of the mat, wherein the first and second sides include upper structures having a sloped lower surface and the third and fourth sides include lower structures having sloped upper surfaces. The sloped surfaces are configured to allow for overlapping with sloped surfaces other like mats for interlocking therewith while forming a generally flat continuous top and bottom surface of the overlapped mats. The mats may be interlocked by a fastening member which fits in aligned openings of the adjacent mats for connection therewith.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. application No. 62 / 368,954 filed Jul. 29, 2016, 62 / 402,391 filed Sep. 30, 2016, and 62 / 402,404 filed Sep. 30, 2016, the entire content of each of which is expressly incorporated herein by reference thereto.BACKGROUND[0002]The present invention relates to a reusable lightweight panel mat system for the construction of equipment support surfaces and temporary walkways and roadways in areas having poor ground integrity characteristics. More particularly, the present invention relates to a reusable system of durable panel mats which are much lighter than wood or wood / steel mats which can be quickly and easily positioned in a single layer to form equipment support surfaces, walkways or roadways and which can thereafter be easily removed and stored until needed again.[0003]While conventional wood mats provide useful service at a reasonable cost, the wood core can deteriorate over time due to moisture ...

AI Technical Summary

Benefits of technology

This patent describes a panel mat installation system that includes upper and lower structures with alignment tabs and slots for easy alignment and interlocking of the mat overlapping areas. Different size mats can be used for faster construction, and equipment can reclaim the mats. The system enables faster and easier installation of temporary flooring covering the entire space. The technical effect of this patent is to provide a more efficient and secure method for installing panel mats in protective areas.

Problems solved by technology

While conventional wood mats provide useful service at a reasonable cost, the wood core can deteriorate over time due to moisture causing gradual rotting and degradation of the wood material.

This causes the mat to be discarded, because unlike some of the other materials that are used on the upper and lower layers of the mat, the core cannot be replaced without essentially making an entirely new mat.

Also, wood mats generally require heavy equipment for installation due their weight and bulk.

And of course cost is a factor in determining the selection of alternate materials, as it is not cost-effective to provide a mat that is multiple times more expensive than one that can be made of wood.
